| Spec score · In-Memory Databases | 8.1 (#9) | 7.4 (#19) |
| Architecture | Dragonfly uses a multi-threaded, shared-nothing architecture that processes work across CPU cores. | Its MVCC architecture allows snapshot queries, including SCAN and KEYS, to run concurrently without blocking existing workloads. |
| Deployment | Dragonfly can be run locally via Docker, and its single binary can be deployed via Docker, Kubernetes, or elsewhere. | Officially managed download options include Docker images, Ubuntu and Debian packages, CentOS RPM packages, and source builds. |
| Integrations | Dragonfly supports Prometheus monitoring without an agent and can read and write snapshots to S3-compatible storage. | Because KeyDB is Redis-compatible, the maker says Redis client libraries can also be used with KeyDB. |
| Performance | The features page states Dragonfly can deliver millions of queries per second per instance and sub-1ms P99 latency. | The maker says a single KeyDB node benchmarks at over 1 million operations per second and that its multithreaded design outperforms Redis per node. |
| Product | Dragonfly is a modern in-memory data store for real-time workloads, caching, feature stores, and job queues. | KeyDB is a high-performance, open-source database and a drop-in alternative to Redis. |
| Security | Dragonfly Cloud lists RBAC, ACL, user access management, and administrative audit logs as security controls. | KeyDB offers TLS support for client connections, replication links, and the cluster bus, and its security guidance recommends restricting access to trusted clients. |
| Support | Dragonfly Cloud offers support from its engineering team backed by contractual SLAs; its pricing page also lists dedicated support for Business. | Support is community-based and managed by the KeyDB team at Snap; the maker says paid support services are unavailable. |
